Hi Cykron, I'm glad you're enjoying my game so far!
The passcodes for Luna can all be found on the RM forums thread here - the original intent was to make a Discord and put out monthly codes for random items and transmogs, but I got very sidetracked haha. Off the top of my head, two of the codes are 10031998 and 0251380.
Please feel free to leave any feedback here or on the forums! :)
